A decoction of the bark is used as eye drops to treat inflammations of the eyes.Berberine, universally present in rhizomes of Mahonia species, has marked antibacterial effects and is used as a bitter tonic. Since it is not appreciably absorbed by the body, it is used orally in the treatment of various enteric infections, especially bacterial dysentery. It should not be used with Glycyrrhiza species (Liquorice) because this nullifies the effects of the berberine. Berberine has also shown antitumour activity. The root and root bark are best harvested in the autumn.
Cuttings of half ripe wood 15cm long, July in individual pots in a frame. Division of suckers in spring. Whilst they can be placed direct into their permanent positions, better results are achieved if they are potted up and placed in a frame until established.Leaf cuttings in the autumn.

The plant is slightly tender in Britain though it does well in Cornwall. It under performs in areas where temperatures regularly fall below -10°c. The young growth in spring can be damaged by late frosts[K]. Hybridizes freely with other members of this genus. The flowers have a delicate sweet fragrance. At least one named variety has been developed for its ornamental value. 'Maharajah' appears to be hardier than the type species. Closely allied to M. acanthifolia (which is quoted as a synonym of this species in some books). The differences stated between the two species do not hold true in the wild but in cultivation M. acanthifolia has leaflets with a dull surface, flowers in the autumn and is hardier than many of the spring flowering introductions of M. nepaulensis.Resistant to honey fungus.
